## Unscramble the Blue Letters

And finally, out of dpeoasetrin, I said, "Well, let me explain Georg Cantor in 1877." And I started explaining why I was there in Africa, and they got very excited when they saw the Cantor set. And one of them said, "Come here. I think I can help you out here." And so he took me through the initiation ritual for a bmaana priest. And of course, I was only irenteetsd in the math, so the whole time, he kept shaking his head going, "You know, I didn't learn it this way." But I had to selep with a kola nut next to my bed, buried in sand, and give seven coins to seven lepers and so on. And finally, he revealed the tutrh of the matter. And it turns out it's a pseudo-random nebumr generator using deterministic chaos. When you have a four-bit symbol, you then put it together with another one sideways. So even plus odd gives you odd. Odd plus even gives you odd. Even plus even gives you even. Odd plus odd gives you even. It's addition modulo 2, just like in the parity bit cehck on your computer. And then you take this symbol, and you put it back in so it's a self-generating diversity of symbols. They're truly using a kind of dinteirmsietc coahs in doing this. Now, because it's a binary code, you can actually implement this in hardware — what a fantastic teaching tool that should be in afiacrn engineering soholcs.

## Original Text

And finally, out of desperation, I said, "Well, let me explain Georg Cantor in 1877." And I started explaining why I was there in Africa, and they got very excited when they saw the Cantor set. And one of them said, "Come here. I think I can help you out here." And so he took me through the initiation ritual for a Bamana priest. And of course, I was only interested in the math, so the whole time, he kept shaking his head going, "You know, I didn't learn it this way." But I had to sleep with a kola nut next to my bed, buried in sand, and give seven coins to seven lepers and so on. And finally, he revealed the truth of the matter. And it turns out it's a pseudo-random number generator using deterministic chaos. When you have a four-bit symbol, you then put it together with another one sideways. So even plus odd gives you odd. Odd plus even gives you odd. Even plus even gives you even. Odd plus odd gives you even. It's addition modulo 2, just like in the parity bit check on your computer. And then you take this symbol, and you put it back in so it's a self-generating diversity of symbols. They're truly using a kind of deterministic chaos in doing this. Now, because it's a binary code, you can actually implement this in hardware — what a fantastic teaching tool that should be in African engineering schools.
